I did the following steps:
- downloading the latest version of Eclipse (Photon-Eclipse Modeling Tools)
- install "CDO R20180613-0111->Net4j DB Framework->Net4j DB Framework PostgreSQL Adapter" from install new software in Eclipse
- create a new Java Project (called myProject)
- download PostgreSQL JDBC Driver from "https://jdbc.postgresql.org/download.html"
- create a lib folder in the myProject and past postgresql-42.2.5.jar into it, and add it to build path of the project
- create a new folder named "config", and create an xml file under the folder
- fill the xml file as follows:
- create a new Launch Configuration (Eclipse Application)
* in the main tab, select "Run an Application" and change is to "org.eclipse.emf.cdo.server.app"
* in the arguments page, in VM arguments, past "-Xms40m -Xmx1024m -Ddebug=true -Dnet4j.config=${resource_loc:/myProject/config} -Dorg.osgi.service.http.port=8080"
The content of XML file:
------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<cdoServer>
<acceptor type="tcp" listenAddr="0.0.0.0" port="2036"/>
<repository name="demo">
<store type="db">
<mappingStrategy type="horizontal"/>
<dbAdapter name="postgresql" />
<dataSource class="org.postgresql.ds.PGSimpleDataSource"
serverName="localhost"
portNumber="5432"
databaseName="cdoRun"
<!--createDatabaseIfNotExist="true"-->
user="postgres"
password="12345"/>
</store>
</repository>
</cdoServer>
------------------------------------------------------------------------------
By running this project, I get the following error:

Did I do wrong any step? Should I do anything else?
It work correctly on H2 database. But, using PostgreSQL?!
Thank you for your help
